The scene from the short story The Bully And The Crazy Boy, where the human fleet fights an all or nothing battle against aliens who wish to conquer and enslave us. The aliens have better technology and may even be more intelligent - but humans have the advantage of being irrational, by their standards. They’d have given up and surrendered into slavery - not do things like surrender a space station, let occupation troops board and then blow it up. Or, in the case of the last battle, lure the alien fleet in, then send in suicide ships at a third of the speed of light, all targeted on the same spot, in a converging sphere all timed to arrive at the same instant. One VERY impressive explosion later, both fleets are dead from the released radiation.
Except for the command ship, which realized what was happening in time to evade at high gravity acceleration - which is when the captured human Admiral bites down on a tooth filled with berserker drug, escapes his restraints, disables or kills his guards and the alien commander, and ignoring his fatal wounds under the drug heads for the fusion room. “And soon, the fury of unchained atoms conquered all”.
Watching the reaction of Pavel Young, Earl North Hollow, as he remembers the duel between Honor Harrington and Denver Summervale.
I should be ashamed of how much I love that scene. I should be.
The ‘Stobor’ attack in Tunnel in the Sky. Also the scene where the gate opens again and Rod is thrust back into adolescence. “I can’t stand it!”
“The Tale of the Adopted Daughter” in Time Enough for Love. Especially the final couple of scenes of the story.
The opening attack on the Skinnies in Starship Troopers: “I’m a ten second bomb! I’m a nine second bomb!”
Several great scenes from Have Space Suit - Will Travel - The treks on the moon and on Pluto, the moment when Kip looks up and realizes he’s no longer in his own galaxy, the speech near the end.
This is vaguely remembered since it’s been a while, but it’s from A Deepness In the Sky by Vernor Vinge, where humans come into contact with a race of spider-like sentients. Both civilizations constantly have to struggle to overcome the instinctive revulsion they feel for the other’s appearance. There’s a scene where a human is talking to a Spider, and suddenly realizes the Spider is crying. That broke my heart, and I’m an arachnophobe.
I liked the ending to it’s sequel, A Fire Upon the Deep, where the galaxy wide AI is wiped out along with a myriad of other technological civilisations, and then the contrast with the new way of life on the planet of the Tines.
I always liked it where Capt. Nemo gives Prof. Aronax a view of the Nautilus’ nuclear reactor (in the 1953 film “20,000 Leagues under the Sea”).
That was cool!
As for Contact, “First rule of government spending: Why build one when you can build two for twice the price. They still want an American to go, Doctor. Want to take a ride?” That whole scene is wonderful.
The thing I loved about that movies was when it won the Hugo at Chicon 2000. David Howard was there and was really psyched to win the Hugo for the movie.
